Cementless, screwless dental abutment system and method of release

Abstract

A Morse taper dental implant providing two or more Morse taper interactions to secure a dental abutment within an implant and beneath a prosthesis. The implant (or anchor) penetrates the jawbone. The abutment having a conical male Morse taper component positions within a female socket forming part of a prosthesis. The abutment comprises an abutment platform from which a conical male Morse taper component extends for creating a second Morse taper interaction with a female socket. At least one aperture forms in the female socket to enable an implement to pass through for engaging the abutment, so as to release the Morse taper interaction(s).

What is claimed is: 
     
         1 . A dual Morse taper dental implant abutment assembly, the assembly comprising:
 a cylindrical implant comprising a threaded outer surface, the threaded outer surface being notched, wherein the implant defines a hollow interior cavity for receiving and mating with a tapered abutment;   a tapered abutment comprising:
 a conical narrow abutment end, the narrow abutment end adapted to position within the hollow interior cavity and form a Morse taper friction fit with the implant, 
 a shaft extending below the narrow abutment end, 
 an abutment platform disposed between the implant and a female socket; 
 a conical male component upwardly protruding from the abutment platform, the male component adapted to position within a hollow recess defined by the female socket and form a Morse taper friction fit, 
 a socket head disposed above the male component; 
   a conical female socket defining a hollow interior recess for receiving and mating with the male component of the abutment and for forming a Morse taper connection therewith, the female socket component defining one or more apertures adapted to allow a user to engage the female socket component with an implement adapted to release the Morse taper friction fit;   wherein the female socket component defines an open top aperture; and   a crown affixed to an exterior surface of the female socket component.   
     
     
         2 . The assembly of  claim 1 , further comprising a tooth-like prosthesis defining a hollow interior cavity for mating with an outer conical surface of the female socket. 
     
     
         3 . The assembly of  claim 2 , wherein the tooth-like prosthesis mates with the outer conical surface of the female socket using a third Morse taper friction fit. 
     
     
         4 . The assembly of  claim 1 , wherein the open top aperture is hexagonal in shape through a cross section and adapted to apply torsional force to the female socket component when engaged with a male hexagonal implement. 
     
     
         5 . The assembly of  claim 1 , wherein a lingual side of the female socket defines a threaded aperture for engagement with a plunger. 
     
     
         6 . The assembly of  claim 2 , wherein the tool passes through the at least one aperture in the female socket to engage the socket head. 
     
     
         7 . The assembly of  claim 6 , wherein the tool engages the axial bore to release the Morse taper friction fit between the female socket and the abutment. 
     
     
         8 . The assembly of  claim 1 , wherein the implant and abutment are fabricated from titanium. 
     
     
         9 . The assembly of  claim 1 , wherein the female socket component defines two diametrically opposed apertures on the outer surface. 
     
     
         10 . The assembly of  claim 1 , wherein the socket head is a hexagonal head. 
     
     
         11 . The assembly of  claim 1 , wherein the abutment further comprises an uninterrupted flange disposed above the socket head. 
     
     
         12 . The assembly of  claim 1 , wherein the shaft comprises a tang. 
     
     
         13 . A Morse taper dental implant abutment assembly, the assembly comprising:
 a cylindrical implant comprising a threaded outer surface, the threaded outer surface being notched, wherein the implant defines a hollow interior cavity for receiving and mating with an abutment;   a tapered abutment comprising:
 an abutment platform disposed between the implant and a female socket; 
 a conical male component upwardly protruding from the abutment platform, the male component adapted to position within a hollow recess defined by the female socket and form a Morse taper friction fit therewith, 
 a socket head disposed above the male component, the socket head defining an axial bore; 
   a female socket defining a hollow interior recess for receiving and mating with the male component of the abutment and for forming a Morse taper connection therewith, the female socket component defining one or more apertures adapted to allow a user to engage the female socket component with an implement adapted to release the Morse taper friction fit; and   a crown affixed to an exterior surface of the female socket component.   
     
     
         14 . A Morse taper dental implant abutment assembly, the assembly comprising:
 a cylindrical implant comprising:   a threaded outer surface, the threaded outer surface being notched, wherein the implant defines a hollow interior cavity for receiving and mating with an abutment;   an abutment platform disposed between the implant and a female socket;   a conical male component upwardly protruding from the abutment platform, the male component adapted to position within a hollow recess defined by the female socket and form a Morse taper friction fit therewith,   a socket head disposed above the male component, the socket head defining an axial bore;   a female socket defining a hollow interior recess for receiving and mating with the male component of the abutment and for forming a Morse taper connection therewith, the female socket component defining one or more apertures adapted to allow a user to engage the female socket component with an implement adapted to release the Morse taper friction fit; and   a prosthesis affixed to an exterior surface of the female socket component using a third Morse taper.
